Quizplus · Accepted Answer

To balance the equation, we need to make sure that the number of Fe atoms and the number of sulfur atoms are the same on both sides. We can achieve this by adding a coefficient of 2 in front of FeS and a coefficient of 3 in front of Fe. This gives us:

2FeS + 3C -> 2Fe + 3CO

Now the number of Fe and S atoms are balanced, and we can see that the coefficient of iron oxide is 0, as it does not appear in the balanced equation. Therefore, the answer is C.
